ACER INCORPORATED
2017 RESPONSIBLE MINERALS REPORT
Introduction
Acer has developed this Responsible Minerals Report (RMR), covering the period from January 1
to December 31 of 2017, for the purpose of describing our due diligence efforts on the source andchain of custody of the gold, columbite-tantalite (coltan), cassiterite, wolframite, tantalum, tin,
and tungsten (collectively referred to as “3TG”) contained in our products that we have reason tobelieve may have originated from the Democratic Republic of the Congo (“DRC”) or an adjoining
country (collectively defined as the “Covered Countries”) and may not have come from recycled or
scrap sources. In addition, Acer began investigating potential due diligence practices to address
other priority minerals in Acer’s supply chain that have been determined to originate from
Conflict-Affected and High-Risk Areas (CAHRA). These include the cobalt supply chain as well as
tin sourced from Indonesia (priority minerals). The efforts associated with developing these due
diligence practices are also described in this report.
Throughout the report, various terms will be used to describe the minerals due diligenceprograms for Acer. The term “responsible minerals” generally refers to Acer’s minerals due
diligence programs. The term “priority minerals” includes minerals that Acer has determined tohave a risk of originating from CAHRAs, and finally, “conflict minerals”, which refers specifically tothe portion of our program and activities related to the sourcing of 3TG from the DRC.
Founded in 1976, today Acer is one of the world’s top ICT companies and has a presence in over
160 countries. As Acer looks into the future, it is focused on enabling a world where hardware,
software and services will infuse with one another to open up new possibilities for consumers andbusinesses alike. From service-oriented technologies to the Internet of Things to gaming andvirtual reality, Acer’s 7,000+ employees are dedicated to the research, design, marketing, sale,and support of products and solutions that break barriers between people and technology. Please
visit www.acer.com for more information.
Reasonable Country of Origin Inquiry (RCOI)For Conflict Minerals, Acer conducted a reasonable country of origin inquiry (RCOI) that employed
a combination of measures to determine whether the necessary 3TG in Acer’s products originatedfrom the Covered Countries. As a member of the Responsible Minerals Initiative (RMI), formerly
the Conflict-Free Sourcing Initiative (CFSI), Acer’s primary means of determining country of origin

of necessary 3TG was by conducting a supply-chain survey with direct suppliers using the RMI
Conflict Minerals Reporting Template (CMRT). The smelters or refiners (SORs) that were identified
as part of this supply chain survey were compared to the list of known SORs that is maintained by
the RMI and those that have had their mines of origin verified by the Responsible Minerals
Assurance Process (RMAP), formerly the Conflict-Free Smelter program (CFSP).
When country of origin is unable to be determined from the CMRT or validated by the RMAP, Acer
turns to other forms of due diligence to conduct its RCOI. This includes direct contact with the
SORs, review of audit reports from supply chain validation programs similar to the RMAP, orreview of outreach efforts by industry-led programs, such as the RMI. In 2017, Acer was able toidentify 298 SORs in its supply chain. Out of 298 total SORs, 248 were validated by the RMAP. Of
the remaining 50 SORs, Acer was able to determine the country of origin for 20, leaving 30 thatremain unknown.
Due to the results of its RCOI, Acer has reason to believe that in some cases, its necessary 3TG
may have originated in the DRC or Covered Countries and has reason to believe that they may not
be from recycled or scrap sources. Consequently, Acer has exercised due diligence on the source
and chain of custody of its necessary 3TG that conforms to a nationally or internationallyrecognized due diligence framework, and describes those activities in this RMR.
Design of Acer’s Due Diligence Measures
Acer developed and implemented a responsible minerals due diligence program to help protect
human rights and to avoid contributing to conflict in the DRC or Covered Countries as a result ofits decision when sourcing the necessary 3TG for the manufacture of its products. In 2017, Acerbegan the process to expand the program to address child labor in the DRC related to cobalt
mining and the environmental impacts and safety concerns of tin mining in Indonesia. We are still
actively in the middle of this program transition as new processes, tools, verification programs arebeing developed and piloted. Acer designed its due diligence measures to be in conformance with
the internationally recognized due diligence framework in the OECD Due Diligence Guidance for
Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (“OECD
Guidance”) and related Supplements for each of the minerals as they relate to downstream
companies in the supply chain.
As a brand company, Acer’s supply chain has multiple tiers between the company and the mines.
Acer does not purchase raw ore or unrefined 3TG or other priority minerals, and does not directly2purchase materials in the DRC, Covered Countries, or other CAHRAs. The origin of 3TG and otherpriority minerals cannot be determined with any certainty once the raw ores are smelted, refinedand converted to ingots, bullion or other mineral containing derivatives. The SORs areconsolidating points for raw ore and are in the best position in the supply chain to know the originof the ores. Our supplier engagement includes the suppliers with which Acer has a direct
relationship and has influence over purchasing decisions. These suppliers are considered first tierand we rely on them to help us identify and assess the risk in the supply chain and provide
information on the SORs that supply the priority minerals contained in our products.
Acer’s due diligence includes the following elements of the 5-Step OECD Framework:
1. Establish strong company management systems;
Adopt and commit to a supply chain policy for identifying and managing risks, structureinternal management systems to support supply chain due diligence, establish a system ofcontrols and transparency over the supply chain, strengthen company engagement with
suppliers, and establish a grievance mechanism.
2. Identify and assess risks in the supply chain;
Identify the SORs in the supply chain, identify the scope of the risk assessment of themineral supply chain, assess whether the SORs have carried out all elements of due
diligence, and where necessary, carry out joint spot checks at the mineral SOR’s own
facilities.
3. Design and implement a strategy to respond to identified risks;
Report findings to designated senior management, devise and adopt a risk management
plan, implement the risk management plan, monitor and track performance of risk
mitigation, report back to designated senior management and consider suspending or
discontinuing engagement with a supplier after failed attempts at mitigation, andundertake additional fact and risk assessments for risks requiring mitigation or after achange of circumstances.
4. Carry out independent third-party audit of smelter/refiner’s due diligence practices;
Plan an independent third party audit of the SOR’s due diligence.

35. Report annually on supply chain due diligence.
Annually report or integrate, where practicable, into annual sustainability or corporate
responsibility reports, additional information on due diligence.
Description of Due Diligence Measures Performed
During the reporting period, Acer performed the following due diligence measures:
1. Established strong company management systems



Continued support of an internal team that includes oversight by senior staff tomanage all aspects of Acer’s responsible minerals due diligence program;
Revised Acer’s conflict minerals policy and internal procedures to broaden thescope of Acer’s due diligence program to include a focus on other priority minerals
that may have originated from CAHRAs. The revised documents, now titledResponsible Minerals Policy and Responsible Minerals Procedure, were necessary
to ensure continued relevancy as the program continues to become moreprogressive (policy available on Acer’s sustainability website);
Continued to maintain and monitor a grievance mechanism via Acer’s general
corporate responsibility email address (cr@acer.com) to be used specifically by any
interested party (e.g. affected person or whistleblower) to raise concerns regarding
business conduct in Acer’s supply chain, including in relation to the extraction andsupply of minerals;Continued to review the RMI Grievance and Complaints Mechanism results to be
informed of the issues and the steps taken to address the matters, as well as
identify any issues where Acer may directly support; andThrough the annual supplier CSR communication meeting, Acer provided follow-up
training on its responsible minerals policy, procedure and the global trend to all of
the internal personnel with responsibility over responsible minerals program
activities as well as all of the 1st tier suppliers over which Acer has direct influence.

2. Identify and assess risks in the supply chainConducted Acer’s sixth conflict minerals survey, requesting information on Acer’s
supply chain using the CMRT and received 100% direct supplier response rate. Acer
will continue to build capacity with these suppliers to ensure a response during the
4

next survey round. We increased the response rate from 95% to 98% in 2017. For
the suppliers that did not respond, we deducted points from their 2017 CSR
scorecard to guide them to take actions to complete the CMRT;
Contributed to the development and initial pilot of the RMI Cobalt Reporting
Template (CRT) and identified an initial list of the cobalt refiners in Acer’s supply
chain;
Consolidated the supplier survey responses and compared the results with the RMI
known SOR lists and the RMAP to verify true SORs, mines of origin, and to
determine the conflict-free status for 3TG;
Acer continues to conduct audits to verify the presence of an implemented due
diligence program, including the existence of their own conflict or responsible
minerals policies, evidence of the design and implementation of supply chain due
diligence program that includes a risk management plan to identify and mitigate
risks, and existence of conflict or responsible minerals reporting. Acer identified
two suppliers via audits that one did not have evidence of a conflict minerals policy
and the other did not have due diligence procedures in place. Acer worked withthe suppliers to establish conflict minerals policies and due diligence procedures to
identify 3TG smelters and eliminate conflict SORs from the supply chain. Acercontinues to monitor, audit and measure the due diligence performance of our

direct suppliers.
Continued conducting research on alleged SORs, identifying SOR alias names andrelating them to alleged or true SORs, contacting them via telephone and/or email
to verify them as true SORs and to encourage them to cooperate with the RMI andparticipate in the RMAP, and assisting SORs with initiating participation in the
RMAP; andContinued to direct suppliers to cease sourcing materials from high-risk SORs thatchoose not to participate in the RMAP.
Acer began using the Standards Comparison and Risk Readiness Assessment (RRA)
tool offered through the Responsible Business Alliance (RBA). The tool allows Acer
to compare suppliers’ performance across many different standards, initiatives andcertifications, improving our ability to assess and manage risk in our minerals
supply chain. At the time of the writing of this report, Acer has connections with 86
smelters and has received 81 RRAs.

53. Design and implement a strategy to respond to identified risksContinued our supplier feedback process, which includes specific line-by-line statusof each SOR identified by our suppliers asking them to review and engage withwhom we identified for “Outreach” as part of Acer’s conflict minerals due diligenceprocess;
Continued to measure conflict minerals key performance indicators (KPIs) within
Acer’s supplier CSR scorecard to minimize risk by driving better due diligence andreporting within the supply chain. Acer saw an improvement of the scores for“good “category, on average, from 9.2 to 9.3. A summary of the results of our
supplier CSR scorecards is provided in Table 1 below; andTable 1: CSR Scorecard Results

Updated Acer’s risk management plan to begin the broadening of the scope toinclude other priority minerals and to maintain consistency with the types of risks
identified through Acer’s due diligence program. The plan includes a list of
conditions which constitute high risk conditions for Acer, recommended mitigation
actions and KPIs, where applicable, to measure progress.
Continued reviewing the RMI’s Grievance & Complaints Mechanism report toidentify potential issues that may exist in Acer’s supply chain and to support
mitigation where applicable.
On April 6, 2018, at the time of the writing of this RMR, the US Government
designated seven Russian oligarchs and 12 companies they own or control, 17senior Russian government officials, and a state-owned Russian weapons trading
company and its subsidiary, a Russian bank. The individual Viktor Vekselberg andcompany RENOVA GROUP was designated on the Specially Designated Nationals
and Blocked Persons list (SDN list) and was subjected to sanctions by the US
Government. The Renova Group is in direct control of the gold refiners JSC
Ekaterinburg Non-Ferrous Metal Processing Plant (CID000927) and Safina A.S.
(CID002290). As a result, the refiners were removed from the RMI’s Conformant
List. Immediately following this designation, Acer requested that all suppliers

6immediately cease all business with these refiners, in the manufacture of Acer
products.
4. Carry out independent third-party audit of smelter/refiner’s due diligence practices
Continued financial support of the RMAP as an active member of the RBA.

5. Report annually on supply chain due diligence

Published an updated list of known SORs, which now include cobalt refiners, thathave been identified in Acer’s supply chain as a result of its due diligence measures,along with a status of each SOR (see Appendix B); andReported on Acer’s supply chain due diligence via this RMR.

In-Region Clean Minerals Trade
Acer continues to believe that projects and organizations that seek to boost economic
development, help stabilize the Great Lakes Region, as well as develop systems that feed
into the CFSI tools and processes are essential. In addition, Acer realizes that mining is anintensive process involving social and environmental risks that must be managed andinvolves metals and minerals that extend beyond 3TG and the DRC. As a result, Acerfollows and/or supports the organizations below.
Monitors the activities of the ICGLR-OECD-UN Joint Forum on Responsible Mineral
Supply Chains to learn about experiences with regards to implementing the OECD
Guidance and opportunities to contribute to in-region programs; andContributes funding and participates as a member of the Public-Private Alliance for
Responsible Minerals Trade (PPA), an organization whose goal is to award funding
for in-region programs that seek to spur economic development and develop
minerals tracing systems

Results of Due Diligence Measures
As a result of its due diligence measures in 2017, Acer was able to identify 298 unique 3TG and 2
cobalt SORs in its supply chain that it has reason to believe are legitimate SORs. Acer based thisdecision off of the information received through the consolidation of its supplier survey responses
and industry information made available to it through its RMI membership and working group
participation.
For the 2017 reporting year, Acer is also providing an update to its progress year-over-year (Figure1) and individual metal performance for the current reporting year (Figure 2). Both charts include
the SOR status as of April 23, 2018 and clearly show the excellent progress Acer has made as aresult of its due diligence efforts.

Outreach: Smelters or refiners that have not agreed to participate, but Acer is assisting with targeted outreachAcer included the following appendices to this RMR that provide additional details on the direct
suppliers and SORs in Acer’s supply chain:Appendix A – Supply Chain Indicators – additional metrics Acer has identified to trackprogress within its 3TG supply chain.
Appendix B – Smelter/Refiner List & Countries of Origin – the complete list of SORs thatwere confirmed to be part of Acer’s supply chain during the 2017 reporting period,
including their location and status. The list also includes the known countries of origin for
those SORs whose mineral sourcing origins have been validated by the RMAP.

While experiencing success, we have also begun to realize the challenge associated with thesmelters that have yet to cooperate and those that have participated in the past, but may waiveron participation in the future. The supply chain is very dynamic and due diligence is an ongoingprocess that if working properly will continue to identify risks and opportunities for mitigation. It
has become apparent to Acer, that a quantitative goal of 100% conformant smelters is a moving
target and is not the right measure of success for our program. Alternatively, a qualitative
measure of the ability of our due diligence process to identify and respond to risks is preferred
and will be implemented going forward.

9

Acer will always reach toward the goal of having 100% of smelters engaged in the RMAP, either
compliant or participating in the process with the goal of becoming compliant. However, due tothe dynamic nature of our supply chain and the existence of a due diligence process that identifies
risk mitigation opportunities, it is realistic to assume that there may always be a number ofsmelters that require outreach or are in the process of being added or removed from the supply
chain. In 2018, we will set the target that 90% of smelters are RMAP compliant and 95% areeither RMAP compliant or participating. This allows for a small quantity of smelters to be in therisk mitigation or transition phase, which is are more realistic assessment of the supply chain
characteristics.
Future Due Diligence and Risk Mitigation Measures
Acer will continue to take steps during the next reporting period to improve the due diligence
conducted and further mitigate the risk in its supply chain, including:Continue to review and update Acer’s policies, procedures, risk-management plans, andprogram metrics to ensure they remain progressive, drive continuous improvement, andare tailored accordingly to account for additional risks specific to other priority minerals
and CAHRAs identified by Acer;Support the development of due diligence processes, tools and audit programs for otherpriority minerals through multi-stakeholder processes, such as those coordinated by the
RMI;
Continue to work with suppliers to increase the accuracy of SOR identification, support
SOR engagement, and drive them to source from SORs with a RMAP-conformant status;
Continue to encourage SORs to participate in the RMAP, with the goal of obtaining a
conformant status;
Continue supplier audits to evaluate responsible minerals policies and practices within the
supply chain downstream from the SORs; andContinue to measure and grade the due diligence performance of our direct suppliers
through our corporate social responsibility scorecard, to prioritize responsible minerals
